Jiangsu External Wall Mineral Wool Boards, Which Jiangsu External Wall Mineral Wool Boards Are the Best - Zhongyi Xin Building Materials Co., Ltd.  

Cautionary Notes
Be mindful of rain protection; construction should not be conducted during rain.
2. Insulation must include a moisture barrier for cold storage purposes. In conditions of exceptionally low temperatures, non-resin-based rock wool is used for insulation, and the moisture barrier must also be fire-resistant.
3. When the temperature exceeds a certain level, such as 200℃, it is necessary to add appropriate external insulation to maintain the thickness and density of the rock wool board without alteration.
4. For rock wool insulation for large diameter and flat wall equipment, when the temperature exceeds 200°C, always remember the manufacturer's instructions for rock wool board: install thermal fixing pins (approximately 400mm apart) and ensure the outer protection is tightly sealed.
5. Insulated equipment, insulation nails, and pipelines can accept appropriate coatings for corrosion resistance. Additionally, there should be no leaks. This will achieve a better effect.
6. For rock wool board products susceptible to mechanical wear when used for outdoor insulation, it is advisable to use metal or plastic sheathing. Pay attention to the joint areas, ensure sealing of the seams, and add rubber gaskets as needed. The overlapping of the wrapping layer should not be less than 100mm.
7. When the thermal insulation object is placed at a 90-degree angle and has a certain height, the thermal insulation layer of the mineral wool board must have a locating pin or support ring. The spacing should not exceed 3 meters to prevent the insulation material from sliding down during vibration.
8. To minimize thermal loss, the joints of rock wool boards and felts must be tightly sealed. When there are multiple layers of insulation, the cross joints should interlace to avoid creating thermal bridges. It is essential to eliminate cold bridges during refrigeration.
    

Exterior rock wool board raw materials are made from natural volcanic rock, making them non-combustible building materials and fire-resistant materials.
Primary fire-resistant features:
⚠️ Class A1 fire-rated, effectively preventing the spread of fire.
The size is extremely stable; it will not elongate, contract, or deform in a fire.
High-temperature resistant, melting point above 1000°C.
No smoke or burning droplets/particles produced in fire.
No harmful environmental substances or gases are released in case of fire.
